Shortened clauses, also known as reduced clauses, are a common feature in Dutch grammar. These clauses allow for more concise and efficient communication by eliminating unnecessary words and constructions while still maintaining clarity. Specifically, in Dutch, shortened clauses can occur when the subject of the main clause and the subordinate clause are the same, and the verb in the subordinate clause is an infinitive or a past participle. Mastering shortened clauses is essential for achieving fluency in Dutch, as it will enable you to express complex ideas more easily and naturally.
